We've seen "fly through the universe" video clips before, but
this one is the best yet! Miguel Aragon, Mark Subbarao and Alex Szalay
created this animation above from the most recent data from the Sloan
Digital Sky Survey.

While you gawk at the clip, remember this: each "speck" you
see is a galaxy containing billions of stars. There are about
400,000 galaxies in the animation - a small slice of the universe which
is estimated to contain as many as 500
billion galaxies.
